oa Interim : Interdisciplinary Journal - A comparative study of three ICT network programs using usability testing



The Software Usability Measurement Inventory (SUMI) testing technique is a rigorously tested and validated method to measure software quality from a user perspective. Using SUMI the usability of a software product or prototype can be evaluated in a consistent and objective manner. The technique is supported by an extensive reference database and embedded in an effective analysis and reporting tool. SUMI has been applied in practice in a great number of projects. This article discusses the practical application of SUMI in a operational environment where second year Information Technology students of the Central University of Technology, Free State utilised SUMI as part of their networking subject, System Software 1 to evaluate three Information and Communication Technology network programs. The results, strengths and weaknesses as well as usability improvements are discussed.
